genus of singular curve (with non-ordinary singularity)

[1 Anonymous 2018/09/24(Mon) 01:58:07.66]

y^n = x^m <- has infinitely many integral point. thus is, by Siegel's theorem, of genus 0
y^2 = x^3 + x^2 <- has ordinary singularity only at the infinity point. thus is of genus 0

genus-degree formula for ordinary singularity now fails
